Update to mksh-45.
* [tg] Make ◊‘et -x„ŗprint the commands run in escaped form
* [tg] PS4 in dot.mkshrc is now timestamped
* [tg] The &> GNU bash I/O redir is no longer parsed in -o posix, -o sh modes,
lksh (breaks valid scripts)
* [tg] Implement ${ „ŗ} more efficiently (deleted-open files)
* [tg] For shf, %#s (if you can get it past GCC—‘ printf format attribute)
calls print_value_quoted, ignoring field width and precision
* [tg] Catch „ŗ◊’ypeset =„ŗ(regression) with better error message
* [tg, Tonnerre Lombard] add „ŗ◊Ňoch„ŗalias to dot.mkshrc which just repeats the
last input line with sudo(8)
* [tg] Use unsigned integers for all calculations, to avoid ISO C „ŗ◊∂ndefined
Behaviour„ŗ(and implementation-defined behaviour) throughout (most of) the
code; emulate signed integer arithmetics using unsigned; not-lksh only
* [tg] Emulate signed modulo na√Įvely, for correct sign of the result
* [tg] Add <<< and >>> for ROL and ROR (rotate left and right, respectively)
operations, <<<= and >>> assignments; bitwise AND the RHS of a shift/rotate
op with 31 (not for lksh)
* [tg] Remove a warning by working around a workaround found in dietlibc which
works around a bug in broken software such as GNU tar (really!)
* [tg] Correct and simplify list and categorisation of built-in commands as
POSIX special and ◊∆verything else„ŗplus a flag to keep assignments
* [tg] Handle ((foo)) as „ŗ◊Õet]„ŗinternally to avoid a conflict with
user-defined functions called let (LP#1156707)
* [tg] Clean up the code
